- omit sm-res I I HR AD a lication a may 13 -The invention relates to improvements in thread cleaners designed primarily for use upon spinning, doubling and analogous machines, and the Ob ect-Of the lnventlon 1s 5 to provide anew and: improved form of I cleaner which may be readilyadjusted. for use with threads of different sizes. ,7 With the foregoing and other objects in view, the invention resides in the novel subn) ject .matter hereinafter described Land I clamping the scra-pingblades in adjusted position. 7 I

In the drawingsabove br efly described,

the preferred form of construction has been illustrated, and while. this construction will be hereinafter specifically described, it is V to be understood that within the scope of the invention as claimed, variations may be made. y

In the drawing above briefly described, the numeral 7 designates an appropriate base to which a fixed scraping knife 8 is secured in anydesired'manner. the upper side of the plate? is provided'with upstanding parallel fianges9 between which the lower end of the blade 8 is snugly received, said blade end being secured between said flanges by any desired fastening means,

such as the screw 10. When such a screw is used, its removal permits the substitution of a newblade for one which has become worn.

A flat vertical sleeve 11 slidably surrounds the blade 8 andhas flared, thread receiving throats 12 formed in its opposite sides, the inner ends of these throats being preferably enlarged somewhat as seen at 13 The thread scraping edge 14 of the fixed blade 8 is disposed at one side of the throats'12, and a thread scraping edge 14: of a *IIIOV', able blade 8 is disposed at the opposite side of said throatsf This blade 8 is rigidly secured in the sleeve 11 and contacts snugly with opposed fiat sides and with one edge of the'latter. Preferably, a screw 10 is Preferably,

The thread is guided between the scraping edges 1414 l$ by suitable guides (not shown) disposedat oppositefsides of the device, and said blades serve to effectively-r I move'any' enlargements whlch would cause trouble if permittedto pass. -Whenever any of the materialscraped fromthe thread, so 195 v accumulates between the edges -14 l14,"as to interfere with operation of the cleaner, a gauge/or the like maybe used to [force edges 1ll4 are formed with opposed notches 14, providing ample space through-" v forced materialrnay be which the inwardly remoyed v c v I I While any desired lockingmeans may be provided for the set screw. 15,"I prefer the construction shown in Fig. 6, wherein the screw has a cylindrical bore 17 to receive the key 18.- The-screw 15"has at-itsinner enda longitudinalnotch19 and the key has pivl i 110 oted at 20 ina notch in its cylindrical end,

When the key is inserted in the bore 17, the dog isin longitudinal alinement with the key but when the dog strikes the blade or knife 8 and the key is rotated, the dog swings on its pivot and its free end enters the notch 19 to cause the set screw to rotate with the key. The shape 7 and mounting of the dog is such that it can the details disclosed, they are preferably followed. However, within the scope of the inventionas claimed, variations may be made as above stated.
